SPINNING MACHINE.

Application filed March 6, 1925. Serial No. 13,546.

To all whom, t may concern! Y Be it known that I, WILLY FREUND, a citizen of the German Republic, residing at Chemnitza Saxony, Germany, have invented certain new and useful Improvements in Spinning Machines, of which thefollowing is a specification.

This inventionv relates 'to a spinning apparatus of the kind in which the spindle is fitted with a slidable cap between which and a support for said cap the yarn is led, and the vinvention consists essentially in the provision of a cap support in the form of a plurality of balls or rollers arranged rotat- -ably in a stationary cage4 so that the yarn fis subjected to a succession of instantaneous retardations.

The supporting elements are arranged detachably in the cage s0 that their number can be varied according to the required retardation effect. The capbears against the supports by means of a detach# able rim which can be exchanged to suit the nature of the material.

The invention also includes various other features in connection with the cap and with the support, as will be hereinafter de scribed.

Fig. 1 of the accompanying drawings represents a side view of the cap and its support, partly in section, and

Fig. 2, across-section of the same on a larger scale taken on the line 2-2 of Fig. 1.

Fig. 3 is a partial plan of a ball cageaccording to one construction, and

Fig. 3, a partial plan of another construction.

Fig. 4 is a plan of a roller cage.

Fig. 5 is a sectional side view on a larger scale showing one construction of the ball cage.

Fig. 7 is a plan of the ball cage support.

Fig. 9, a plan of the same.

Figs. 10` 11, 12 and 13 are sectional views showing ball cages of different constructions with resiliently supported rollers.

Fig. 14 is a plan of the arrangement shown in Fig. 12.

Slidably connected to the spindlle 7 is a cap 3 having at its lower edge a detachable rim 11 whereby it rests on a support formed by one or more balls or rollers which are held in and controlled by a cage 12. The yarn is led in between the cap and the support and will ybe subjected, during each revolution of the spindle, to a succession of instantaneous retardations as it moves with the cap over the supporting points. The balls or rollers are arranged so that they can be easily removed and refitted for the purpose of varying their number according to the nature of the yarn and to the desired retardation effect. There may be only a single rowl of balls, as shown in Fig. 3, or, if the rim 11 is wide, two rows` as shown in-Fig. 3a, the balls of different rows being in the latter instance arranged in a staggered position so as to come into play alternately. By this arrangement the retardation of the yarn can be regulated withinr a very wide range.

the all cage. A flanged ring 15, having apertures in which to hold the balls 13, is screwed on to a ball supporting rim 16. A space 17 is formed between the two rings so that the dust can 'be readily discharged through the ring 16 from between the balls 13.

A similar arrangement may be used to take rollers 14 or the like (Fig. 4) instead of balls.

The cage may be connected to the ring Fig 5 shows the preferred construction of rail 18 either direct as shown in Fig. 1, or

through the medium of a ring 20 which is split at 19 (Figs. 6 and 7) so that it can be clamped to the cage. A screw 21, which is fitted in the rail 18, clamps the ring 2() to the cage as well as t'o the rail.

In the arrangementshown in Fig. 1, the cap 3 is formed with a neck 2 into which is screwed. a bushing 4. The latter is formed with conical orilices 5 and with a flat central channel 6 for engagement with the fiat faces 8 of the spindle. The cap can thus be adjusted longitudinally -of the -spindle while it is compelled to participate in the rota tion of the same.

In order to regulate the weight of the a flattened aperture 2-1 whereby the cap is guided on the spindle 7. The block has flanges. to take the screws 29 whereby the elements are connected together. A small space 25 is left between the top flange of the cap and the head of the screw 29 so as to allow a certain amount of free play. There is also an air space 26 left between the rubber ring 22 and the block 23.

The balls 13 may also be elastically supported by means of springs 27 as shown in Figs. 10 to 14. Fig.,10 shows a ball supported vertically in this manner. In Fig. 11 the ball is supported by an obliquely arranged spring and bears against an oblique sur ace on the rim 11 so as to support the cap 3 against horizontal as well as vertical vibrations. The same object is attained by the arrangement shown in Fig. 12 where one ball supports the cap vertically and another horizontally. Fig. 13 also shows two balls one of which supports the cap vertically and the ,other obliquely. Fig. 14 shows the relative position of the balls in the different rows. The springs 27 may be replaced by other cushioning elements such as felt, leather, rubber or the'like. The cushions may be applied to the cage instead 0f t0 the balls.

All -sorts of yarn from the coarsest. to the finest can be spun by means of this arrangement with loose or hard twist, without 1njury to the fibres. High spindle speed is possible, and the yarn can be laid on the spindle or on a cop tube in any suitable manner.
